I blew out Mr Gasket gaskets, Hi-Temp sealants, everything I tried, I blew out. I bought a sheet of laminated aluminum (.048" .003" 9574K32 $56.07). I used a hamner to outline the gasket, hole cutters to cut the large and small holes and tin cutters to cut the outside edge of the gaskets. One year, 5000 miles and no leaks.
